        model_id (str): The model ID of the model for which to
            retrieve the default training metric definitions. (Default: None).
        model_version (str): The version of the model for which to retrieve the
            default training metric definitions. (Default: None).
        hub_arn (str): The arn of the SageMaker Hub for which to retrieve
            model details from. (default: None).
        instance_type (str): An instance type to optionally supply in order to get
            metric definitions specific for the instance type.
        tolerate_vulnerable_model (bool): True if vulnerable versions of model
            specifications should be tolerated (exception not raised). If False, raises an
            exception if the script used by this version of the model has dependencies with known
            security vulnerabilities. (Default: False).
        tolerate_deprecated_model (bool): True if deprecated models should be tolerated
            (exception not raised). False if these models should raise an exception.
            (Default: False).
        sagemaker_session (sagemaker.session.Session): A SageMaker Session
            object, used for SageMaker interactions. If not
            specified, one is created using the default AWS configuration
            chain. (Default: sagemaker.jumpstart.constants.DEFAULT_JUMPSTART_SAGEMAKER_SESSION).
        config_name (Optional[str]): Name of the JumpStart Model config to apply. (Default: None).
        model_type (JumpStartModelType): The type of the model, can be open weights model
            or proprietary model. (Default: JumpStartModelType.OPEN_WEIGHTS).
    Returns:
        list: The default metric definitions to use for the model or None.
